305379e944 devicetree: add first round of dependency ordinal info
Add the first API functions that directly deal with node dependency
ordinals as determined by edtlib:

- DT_DEP_ORD(node_id): node_id's ordinal
- DT_REQUIRES_DEP_ORDS(node_id): list of dep ordinals for node_id's
  direct dependencies
- DT_SUPPORTS_DEP_ORDS(node_id): list of dep ordinals for nodes
  depending directly on node_id
- DT_INST_ equivalents

This is not meant to be an exhaustive set of macros related to
dependency ordinals; rather, it's a starting out point meant to enable
initial struct device dependency tracking work. We can add more if
needed.

c3eef7744a include/devicetree.h: Add DT_ENUM_IDX_OR macro
In case a "required: False" enum binding doesn't mention a
default value, but a default value makes sense to be set in the code,
DT_ENUM_IDX_OR could be used to provide the default idx to be used.

New macro comes with appropriate tests.

e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

922b469fd4 devicetree: add accessors with default values
Add a variety of property and specifier cell accessors that fall back
on a default value supplied by the caller if the devicetree does not
contain the requested data.

This is useful for avoiding use of COND_CODE_1() and similarly tricky
macros in applications and drivers.

fd7447522d tests: devicetree: cleanup / refactor
Move some common macros shared between different unit test functions
up to the top of the file to make them easier to spot and keep them a
bit tidier.

This cleanup excludes macros that are only used for specific purposes
in a single function.
